Module installation 

Functions

choice_categories 🔒

confirm_removals 🔒 ^⚠

Names every installed package the selection no longer holds and asks before removing them; false when the user declines.

finish 🔒 ^⚠

Records the outcome, reopens the cache the worker wrote, and moves on to the summary.

free_space 🔒 ^⚠

None when it cannot be measured, which makes the engine skip its space check.

host_facts 🔒 ^⚠

What the engine cannot find out for itself, since it stays testable off Windows.

installation_page^⚠

Scene 6: apply the selection to the game folder from the cache. It has no Back, Next or Cancel: every phase writes to the game folder and the engine cannot stop between files, and it presses Next itself when the run ends.

start 🔒 ^⚠

Everything it installs from is already in the cache, fetched by scene 4b or already there on the other routes.

start_restore 🔒 ^⚠

Hands the restore the user approved to the worker, its plan unchanged, since the preview they read is that value.
